+ *
+ * Date:    31 July 2002
+ * SUMMARY: Testing regexps containing octal escape sequences
+ * This is an elaboration of mozilla/js/tests/ecma_2/RegExp/octal-003.js
+ *
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=141078
+ * for a reference on octal escape sequences in regexps.
+ *
+ * NOTE:
+ * We will use the identities '\011' === '\u0009' === '\x09' === '\t'
+ *
+ * The first is an octal escape sequence (\(0-3)OO; O an octal digit).
+ * See ECMA-262 Edition 2, Section 7.7.4 "String Literals". These were
+ * dropped in Edition 3 but we support them for backward compatibility.
+ *
+ * The second is a Unicode escape sequence (\uHHHH; H a hex digit).
+ * Since octal 11 = hex 9, the two escapes define the same character.
+ *
+ * The third is a hex escape sequence (\xHH; H a hex digit).
+ * Since hex 09 = hex 0009, this defines the same character.
+ *
+ * The fourth is the familiar escape sequence for a horizontal tab,
+ * defined in the ECMA spec as having Unicode value \u0009.
